Ah, Facebook. You constantly-evolving entity of a social networking site. Facebook only just rolled out their updated photo viewer which sports higher-resolution photos, up to four times the size of before, but have also just thrown in a new tool that enables users to quickly filter out content that hasn't been posted by close friends.

Facebook's web-based portal is now capable of suggesting friends based on interaction frequency, reducing the need for users to manually peruse their entire friends list. This new tool is an extension of Facebook's Close Friends and Acquaintances feature, where it helps users focus on status updates from their closest, and dearest friends.

The new tool is available right now, which you can access from the Friends page under the Acquaintances list as "See All Suggestions".
